STRIP INSTALLATION AND FAS- TENER FOR THE SAME Churchill, Saugus, Mass., assignor to United-Carr Fastener Corporation, Cam'- bridge, Mass., a corporation of Massachusetts Application December 14, 1935, Serial No. 54,493 7 2 Claims. (01. 296-445) My invention relates to the means of attaching a window strip or the like to a support and aims to provide an improved fastener member for that purpose.

- Referring to the drawing in which I have illustrated a preferred embodiment of my invention: Figure 1 is a section of a window channel support, a window for the same, and a window strip secured to the support by means of the fastening members which are shown in elevation;

Fig. 2 is another view' of the installation shown in Figure 1- with the window strips and fastenet members shown in elevation;

Fig. 3 is a view taken on the line 33 of Fig. 2;

Fig. 4 is a view taken on the line 4-4 of Fig. 2; Fig. 5 is an enlarged view of the fastener member illustrated in Figs. 1-4; 1

Fig. 6 is a side view of illustrated in Fig. 5; and

Fig. 7 is a rear view of illustrated in Fig. 5.

The object of my invention is to provide a simple and inexpensive means for attaching a flexible strip or the like to a supportingstructure. My invention is particularly useful as a means for securing a flexible strip or trimming used in connection with an automobile window installation to the framework of the window the fastener member the fastener member channel. This flexible strip is of great importance if installed with an automobile window 'channel as it seals the space betweenthe sides of the channel frame and the window so as to prevent to an appreciable degree the passage of air through those spaces and at the same'time furnishes a smooth anti-rattle runway for the window pane. Due to the fact that my improved clip member is particularly adaptable to the attachment ofa window channel strip to a channel frame, I prefer to describe it in connection with such an installation although there are many other uses to which my fastener could be directed which would fall within the spiritpf this invention.

Referring to Figs. 1-4, which'illustrate apreferred use of my invention, .1 have shown a metal window channel comprising opposite frames I each of which is of U-shaped construction in cross-section. The oppositely disposed inside faces 2 of the frames bound the channel through which the window pane 3 is moved during the raising and lowering of the same. The flexible strip 4 is positioned to seal in effective manner the passages between the frame faces 2 and the window pane, as may be clearly seen in Fig. 1. The strip may be formed in any suitable manner although I have illustrated a part of a substantially tubular construction having slightly flattened sides and an outer covering of a sturdy cloth-like material. In my preferred form I have provided the strip with a core comprising a metal stiffening means 5 for preventing too great flexibility of the part. The nap means 6 extend from one side of the strip, as illustrated in Fig. 1.

The strip is attached to the frame 1 by means of my improved fastening members which are provided with a stud means-l extending through an aperture 8 in the frame in snap fastener action the material of the frame surrounding the aperture, as best illustrated in Figs. 1 and 2. 7

Referring in greater detail to the fastener member, I have illustrated in Figs. 5-7 a clip which is made from one piece of sheet metal face 2 and engaging presenting a flat base plate 9, a resilient attaching portion 1, and a hook-shaped spring clamping means H. In my preferred form the clip is tempered to provide suitable spring action in certain of the parts, as described below.

The attaching portion of my preferred form is pressed from the material of the base plate and provided with a head portion 12 and neck portion l3. The head and neck portions are rendered resiliently contractible by a plurality of slots l4, herein shown as four, which preferably, as illustrated in Figs. 5 and I, extend to or slightly into the base plate. The spring clamping means H is formed integral with the base plate having a hook-shaped arm I5 looped beneath the plate on the opposite side of the plate from the attaching portion. The part I5 is provided at its extremity with an inturned clamping edge l6 for gripping the strip. A slot ll extends from the base plate for a substantial distance into the part l5 for providing an easier working spring action in the clamping means.

In assembling the parts of the installation the flexible strip 4 is forced into the space between the arm l5 and the rear face of the fastener base plate. As the thickness of the strip is slightly greater than the distancebetween the edge I6 and the face of the plate, the arm 15 will be expanded slightly until the strip is secured in correct position, at which time the arm will contract ,so that the edge l6 will grip the strip to hold it firmly against the face of the plate (Fig. 1). The fastener is then broughtup to the aperture 8 of the steel channel frame and the atfastener action thereby causing the window strip 5 2 to be firmly attached in operating position. It is obvious that any number-of fastener members may be used to attach the strip to the frame, but it is necessary that a corresponding number of apertures be located in correct position in the frame supports l to receive the attaching portions of thefasteners.

I have shown in Fig. 1 window strips attached to opposite inside faces of the channel frame so that the trimming is located on both sides of the glass. It is common in automobiles, however, to provide a strip solely on one side ofthe channel, namely against the inside surface of the glass to prevent cold air or dust from entering'the in.- terior of-the automobile, and for that reason I do not wish to be limited to the double window strip installat'on as shown in Fig. 1. Furthermore, I do not wish to be limited to the resilient stud portion, as shown, because it is possible to provide several modified constructions of this portion, any one of which would be equally satisfactory as a means for attaching the fastener to the frame support.

Although I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby, because the scope of my invention is best set forth in the following claims.

I claim:

1. In an installation of the class described, a support having an aperture therethrough, a narrow flexible strip superposed upon said support,

a sheet metal clip, said clip having a base portion located between the support and the strip, a resilient snap fastening means extending from one side of said base portion through the aperture in said support and secured in snap fastening engagement with said support, and a hook-shaped arm connected to said base portion at one end thereof and extending over theedge and one face of said strip and being clamped against that face of said strip with the hook end embedded into the material of the strip to hold said strip securely in position relative to said support.

2. In a window installation of the class described, a window frame support having an aperture therethrough, a narrow flexible window guide strip, a metal snap fastener clip and a window slidable against said window guide strip, said clip having a base portion, a resilient snap fastening means extending from one side of said base portion through the aperture in said support and secured in snap fastening engagement with said support and a compressible clamping means including said base portion as a part thereof, said clamping means being in compressed clamped relation with said strip for securing it to said support, said clamping means having a strip-engaging portion extending therefrom toward and into embedded relation with the strip to prevent the strip from slipping laterally relative to the clip.
